The "x" are your partitions. If you wish to see what numbers there are...after booting with the flash drive type in a terminal sudo fdisk -l (as in lower L). This will list all the partitions, including the USB. Your hard drive will be sda(1,2,3...)

To open a terminal type ctrl+alt+t
sudo fdisk -l
fsck -a /dev/sdaX

When you installed Ubuntu you used a live dvd or live usb, either will work. If you no longer have what you used then make another by either burning an ISO image of Ubuntu onto a DVD or installing the ISO image onto a flash drive.

When in the BIOS was your USB plugged in and did the BIOS see it? ie was it a boot option? If not, check and see if there is a + next to harddrive and if yes click it and promote your USB.
Are you sure the image was installed rather than copied to your USB? How did you install it?

I followed instructions in google and made a liveusb by installing a .iso file into the usb. Ubuntu was installed on the laptop when bought it, so I have no liveusb (I did installed later win 7, than back to ubuntu, I used installation cd, but I already made a live-usb).
The bios see my disk on key, his manufactour written there in the boot options. Two options in boot:
LEGACY boot- with 4 options- I choose usb
and UEFI boot- with only option: (EFI USB1 PATH1 (SANDISK CRUZER BLADE).
What am I doing wrong?

Update- I did it! I'm inside, I'll update, right now checking disc for defects (one of the options that featured there).
2 files with errors found, now I'll try to check what you told me.

So I did the partitions checking first , I'm using sda 1,2 and 5.
Then did the fsck check on each one.
On 1 and 2 it writes in reply- "permission denied while trying to open....you must have r/w access to the filesystem or be root.
On 5- fsck.swap not found.
error 2 while executing fsck.swap...

What does all of that mean?

What you downloaded is the stand alone version. After unzipping it go to the folder where the files were unzipped .

cd /where/you/unzipped/testdisk-7.0
and run
sudo testdisk_static

Using the gui navigator (folder icon) and go to the testdisk-7.0 folder that you unzipped. You should see the file testdisk_static. Right click it and select properties. Copy the location and then open a terminal and paste (shift + ins) that after cd ie

cd /location/of/file

the command line will now read $/location/of/file

type sudo testdisk_static

Accept defaults and you'll get to a point where is has an option p to list files then c to copy them, follow their instructions at the cg site.
